Patients with cervical insufficiency need to go to the hospital as soon as possible within 14-18 weeks of pregnancy for cervical cerclage to preserve the pregnancy. In most patients (with cervical insufficiency), cervical cerclage is usually successful in preserving the pregnancy. Before performing cervical cerclage for cervical insufficiency, a vaginal discharge test is needed to rule out vaginal inflammation. If there is vaginal inflammation, cervical cerclage should not be performed and should be performed only after the vaginal inflammation has been cured. After cervical cerclage, you need to take rest, avoid strenuous exercise, pay attention to the cleanliness of the vulva, prohibit the consumption of spicy and stimulating food, and keep the bowels open.
